In this tutorial post we will be running our first JavaScript program which is a basic Hello World program where we ill simple print Hello World(or any other text) on the browser.
The 2 softwares needed to start of with JavaScript are -
Text Editor : I will be using Visual Studio Code Text Editor which is highly recommended by many specially for Javascript, however you can use any other text editor like Notepad++ or Sublime text etc.
Browser : Of course a browser is needed to load the HTML document and run the JavaScript so I will be using Google Chrome browser. You can use any browser of your choice as most modern browsers have JavaScript enabled by default.
There are 2 ways to include JavaScript in your HTML Document -
Embedding JavaScript in the same HTML document
Using External JavaScript file and linking it in your HTML document.
1. Embedding JS in HTML document -
As you can see in the code below, we are embedding JS code using the script tag of HTML. Usually when the JavaScript code is small it is directly embedded in the HTML document, however, it is not recommended to embed large sized JS code directly in the HTML document as the code becomes un-organized.

2. External JavaScript File -

The fact that the .write() method lets you literally inject new html into your document is mind-blowing! I can already see all the possibilities! Makes me curious how someone can use JS to alter CSS (I know we're gonna get to it). Thanks bro, your lectures are really helping my old brain figure things out 🙌🏽

Well explained!
But it looks awkward when you code at the right side but the output is shown on the left side.
If you have not already recorded all the videos for this tutorial series/playlist then, please, I request, by now, keep the VS Code window opened at the left hand side and the browser window at the right. It will help maintaining our natural spirit of thinking and understanding with more ease and comfort. Its a matter of psychology.

Note: If viewers dislike this comment don't change your way, but if they like then you should think, otherwise it's your choice whether you like my suggestion or not. 😊

Install live server in visual studio code. Live server plugin .. after that you don't need to refresh browser after write new code in VS code. Automatically it will refresh .

Dude, Visual Studio code is not just the next editor, its an IDE and is heavy. Sublime text and notepad++ are text editors.
